Retrograde Intrarenal Surgery for Stone Disease Under Spinal Anaesthesia, A Minimally Invasive Technique. A Retrospective Analysis of 1,467 Cases - Beyond the Abstract

The aim of the current study was to compare Retrograde intrarenal surgery (RIRS) procedures applied under general anesthesia (GA) and spinal anesthesia (SA) with respect to success rates, and complication rates. A retrospective evaluation was made of the data of patients applied with RIRS under SA and GA at two centers between October 2014 and January 2018. The SA and GA groups were evaluated in respect of the parameters of stone-free and complication rates, postoperative pain control, length of stay in hospital.

The stone-free rates were examined of the RIRS procedures applied with SA among the 11 surgeons who participated in the study and experienced at least 100 cases. A total of 1361 patients were included in the study. A stone-free rate of 84.4% was obtained in the whole study sample, as 85.3% in the SA group and 83.5% in the GA group. (p=0.364). No statistically significant difference was determined surgeons who applied RIRS with SA in respect of success and complication rates and operating time (p=0.676). Operating time was determined as 44.2±14.2 mins in the SA group and 49.7±19.1 mins in the GA group (p=0.014). The RIRS method can be applied as safely with spinal anesthesia as with general anesthesia. The success of RIRS under spinal anesthesia was seen to be independent of the surgeon factor, it can be considered a good alternative to general anesthesia.
